BALING-PRESS.

Specification of Letters Patent. Patented Dec, 21 1915.

Application filed April 17, 1914. Serial No. 832,655.

To all whom it may concern:

Be it known that 1, CHARLES L. CooKsoN,

a citizen of the United States, residing at Kansas City, in the countyof Jackson and State of Missouri, have invented certain new and usefulImprovements in Baling- Presses, of which the following is aspeclfication.

This invention relates to baling presses, and my object is to produce aneflicient powerpress of simple, light, compact and strong construction,and which in proportion to its weight and length, has a larger feedopening than any power press of whlch I have knowledge.

A further object is to produce a construction in which the head block iscaused to tilt forward in making its power stroke to cooperate moreeffectively with the folder, and rearward in making its return stroke,to more readily admit of the passageof the baling material from thehopper to the bottom of the baling chamber under the pressure of thefeeder.

With these general objects in view the invention consists in certainnovel and peculiar features of construction and organization ashereinafter described and claimed; and in order that it may be fullyunderstood reference is to be had to the accompanying drawings in which:v

Figure 1, is a perspective v1ew of a baling press embodying my inventionFlg. 2, is an enlarged central vertical section of a part of the presswiththe headblock just about to pass under the folder. Fig. 3, is asimilar view with the head blockin its most advanced position. Fig. 4,is a similar View with the head block almost completely withdrawn. Fig.5, is a cross section on the line VV of Fig. 3. Fig. 6, is acrosssection on the-line VIVI of Fig. 3.

In the said drawings 1 indicates the baling chamber of the machine, saidchamber being of conventional type and mounted upon ,wheels 2. The lowercorner lrons consisting of alined portions 3 and 4, rigidly connected inany suitable manneryprovided they can be separated for convenience ofshipment, and the portions 4 are mounted upon the front wheels 5 andcarry a motor, such as a gas engine 6,'the battery box of the enginebeing shown at 7.

8 is the hopper of ordinary type, thatis, open at one side, as shown, sothat the baling material can be conveniently supplied to the hopper froma feed table, not shown.

9 is an ordinary. hinged carrier for the division block 10, and theadjacent end wall of the hopper is cut down so that the carrier may beswung from the positionshown by Fig. 1 to the position shown by Fig. 3,to dispose the division block in position to be forced out of thecarrier and down into the baling chamber by the feeder, in the customarymanner. Depending into the, baling chamber at the lower edge of thehopper wall which is cutdown, is an ordlnary folder 11, and adjacentthereto are the customary bale-retainers 12.

All of the parts thus fardescribed are of common and well knownconstruction, except that it is new as far as I am aware, to make theframe in sections for convenience of transportation.

Power is transmitted from the engine through belt 13 to wheel 14 mountedon one end of a transverse shaft 15 journaled in bearing 16, securedupon the framework of the bailing chamber at the opposite. side of thehopper from the carrier 9.

17 are gear pinions mounted on shaft 15 and meshing with larger gearwheels 18 journaled on stub-shafts 19, rigidly secured to and projectinginwardly from castings 20, secured to the baling chamber frame and castintegrally-with and at the inner sides of wheels 18 are gear pinions 21,which pinions are disposed or formed eccentrically ofthe stubshafts,.and the inner ends of the latter are diametrically reduced andform journal supports for antifriction rollers 22.

A pitman for transmitting power from the driven eccentric pinions to thehead block, hereinafter identified, embodies longitudinal rack bars 23and substantially elliptic channeled guides 24 inclosing the rack bars,the teeth vof which bars are preferably in the form of steel pins castin the bars. The channeled guides each consist of semicircular ends 25extending concentrically around the end-most pins or teeth of the rackbars, and oppositely bowed portions 26 connecting the said semi-circularportions 25, the said channeled guides snugly receiving the antifrictionrollers 22 on the inner ends of the stub shafts for the purpose ofpreventing undue lateral pressure on the teeth or pins of the rack bars,by the eccentrio pinions. The pitman also embraces a portion 27 alinedwith the rack bar and pivoted on upright 28, carried by the head block29, adapted forreciprocal movement in the baling chamber, and toeliminate friction as far as possible, the head block" is provided withtrack wheels'30 which run upon the bottom plate of the baling cham-'ber. '-To prevent'undue upward movement of the head block,-it isprovided with a stem 31 extending downward through a slot32 in thebottom of the baling chamber and a verticalplane on standards 37 risingfrom.

provided with a' pair [of antifriction rol1- ers 33 for engagement attimes with the bottom ofthe baling chamber or rather with angle-irons 83secured to the bottom of said chamber to stifienthe same. 'Pivoted toportion 27v of the pitman is a pair of links 84, which-are pivotallyconnected-at their upper ends to aswing frame 8 5 having cross piece-36'fulcrumed for movement in '38'are' feeder arms normally restingqon'cross piece 36 and pivoted coincidently with "swing frame 35, to links34; A. clamp plate 39 rests upon feeder arms 38 to hold the samenormallyiupon the cross piece 36 and to permit :said feeder armstoiswing up wardly' from the cross piece, a bolt 40 extends fromthecross pieceup throughclamp s 44 is the feeder provided with 'a'knee 45 Iand pivoted to the outer end of the feeder arms 38, and also at4Z to apair or, links 46 pivoted at their inner ends at 48 tothe upperextremities of standards 87-. The

feeder operates inthecustomary manner and needs no detailed description;

I The head block is equipped with thaws: tomary hinged apron. 49, and,the free "end, of the apron has sliding action on abridge piece '50carried by links 34 to prevent the apron from coming in contact with theteeth of wheels 18.. In operationthe Wheels 18 are driven in the'direction indicated by the arrows and assuming that the head block hasattained its greatest limit of power parent that the endmost rack bartooth, which is engaging the eccentric pinion,- is inengagement with thesame at'its point of I smallest diameter and is swinging around the axisof said wheel in a downward direc-l tion. This action it will be seentends to depress the end of the pitman remote from the head block, thespeed of the depressing movement and of the consequent rear movement ofthe head block, increasing in pro portionto the increase'of diameterofthe pinion until the antifriction rollers 22 pass.
